Slow damping valve closing features

Slow closing check valve muffler can be used in water, sewage, sea water and other media of the drainage pipes, both to prevent the media back, but also effectively limit the destructive water hammer to ensure the safety of the use of the pipeline. Microporous retarded butterfly check valve has the advantages of novel structure, small volume, light weight, small fluid resistance, reliable sealing, smooth opening and closing, wear resistance, long service life, hydraulic pressure and slow closing without media influence. Good energy-saving effect and so on.
